Lockimate - Turn any image into a living lock screen wallpaper

Lockimate turns any still photo into a living lock-screen wallpaper for iPhone. The problem it solves: iOS will only animate a lock screen if the file is a genuine Apple Live Photo — a paired .heic image and .mov clip carrying specific metadata. Most apps in this category either require you to supply your own video clip, or export an .mp4 you then have to run through a separate converter, which usually still fails. iOS gives no error when it refuses; the Live badge simply greys out. This tool simplifies the process.
